ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.

On July 12, 1995, ADAC Laboratories ("ADAC") completed a
series of transactions with Community Health Computing Corp., a Delaware
corporation ("CHC"), including the purchase of 4,000,000 shares of Series A
Preferred Stock of CHC pursuant to the terms of a First Amended Series A
Preferred Stock Purchase Agreement. The total cost of the acquisition to ADAC
was approximately $16.5 million, plus expenses of approximately $1.9 million.
The purchase price paid by ADAC for the Series A Preferred Stock consisted of
the forgiveness by ADAC of certain obligations of CHC and its wholly-owned
subsidiary, Community Health Computing, Inc. ("CHCI"), of approximately
$4,000,000 of principal and interest owed to ADAC under a Post-Petition
Financing Agreement. As of the closing of such transaction, ADAC became the
sole stockholder of CHC.

CHC is located in Houston, Texas, and (with its wholly-owned
subsidiary) develops and markets products for the laboratory and radiology
information systems markets.

The source of funds used for the transactions with CHC was
from ADAC's working capital, including available funds under ADAC's existing
bank credit line.

There has been no material relationship between any of the
officers, directors or principal shareholders of ADAC, on the one hand, and CHC
and its principal shareholders, on the other hand. ADAC has, however, prior to
the closing of these transactions, been a creditor of CHC, having made certain
pre-petition and post-petition loans to CHC just prior to and following its
filing of a petition under Chapter 11 of the federal bankruptcy laws. All
prior shares of CHC were cancelled in connection with CHC's bankruptcy
proceedings.

ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS.

SECURITY AGREEMENT

THIS SECURITY AGREEMENT dated as of July 12, 1995, is made by COMMUNITY
HEALTH COMPUTING, INC., a Texas corporation ("Grantor"), in favor of ADAC

RECITALS

A. On December 7, 1994, Grantor and COMMUNITY HEALTH COMPUTING
CORP., a Delaware corporation ("CHCC"), commenced separate cases under Chapter
11 of Title 11 of the United States Code (the "Bankruptcy Code") by filing
voluntary petitions with the United States Bankruptcy Court for the Southern

cases are now pending as Case Nos. 94-48483-H2-11 and 94-48484-H3-11 and are
collectively hereinafter referred to as the "Chapter 11 Case". No trustee was
appointed, and Grantor and CHCC operated their respective businesses and
remained in possession of their property as debtors-in-possession during the
term of the bankruptcy. At the time this Security Agreement becomes effective,
Grantor and CHCC will be operating their businesses as reorganized Debtors
pursuant to a confirmed Plan of Reorganization (the "Plan").

B. On December 7, 1994, Grantor, CHCC and Lender entered into a
Post-Petition Financing Agreement (the "Post-Petition Financing Agreement")
pursuant to which Lender has provided Grantor and CHCC with debt financing,
secured by a lien on substantially all of their assets.

C. Grantor and CHCC have prepared and reviewed with Lender, and
have filed with the Bankruptcy Court, their proposed Plan, together with a
Disclosure Statement with respect thereto. Capitalized terms used but not
defined in this Security Agreement shall have the meanings given to them in the
Plan.

D. The Plan contemplates, among other things, (i) that Grantor,
CHCC and Lender shall enter into a "Modification of Loan Agreements", pursuant
to which Grantor and CHCC will issue a secured promissory note (the
"Replacement Note") and Grantor and Lender will enter into this Security
Agreement and CHCC and Lender will enter into a security agreement, of even
date herewith (the "CHCC Security Agreement"), in relation thereto, (ii) that
Grantor and Lender shall enter into a "Post-Confirmation Loan Agreement",
pursuant to which Grantor will issue a secured promissory note (the "CHCI
Note") and enter into this Security Agreement, and (iii) that Grantor, CHCC and
Lender shall enter into a Series A Preferred Stock Purchase Agreement (the
"Acquisition Agreement"), providing for (a) the forgiveness by Lender of the
obligations of Grantor and CHCC to pay an aggregate of four million dollars
($4,000,000) of principal and interest owed to Lender under the Post-Petition
Financing Agreement and/or that certain Loan Agreement dated as of November 30,
1994 among Grantor, CHCC and Lender and (b) in consideration of such
forgiveness of indebtedness, the issuance by Grantor to Lender of an aggregate
of four million (4,000,000) shares of a new series of CHCC's preferred stock,
designated Series A Preferred Stock, which, together with any shares of common
stock that may be issued to Lender upon voluntary conversion thereof and
certain options to purchase shares

1.
<PAGE> 6

of common stock to be issued pursuant to Lender's direction, will constitute
all of the outstanding equity securities of CHCC immediately after the Closing.
(The Modification to Loan Agreements, the Replacement Note, the
Post-Confirmation Loan Agreement, the CHCI Note, the CHCC Security Agreement,
this Security Agreement, the Acquisition Agreement and other related agreements
are referred to herein as the "Post-Confirmation Agreements".)

E. Grantor will receive substantial direct and indirect benefit
from the Replacement Note, the Modification of Loan Agreements and other
financial accommodations made by Lender to CHCC pursuant to the
Post-Confirmation Agreements.

F. Lender is willing to enter into the Replacement Note and the
other Post-Confirmation Agreements and to make the loans and other financial
accommodations to Grantor and CHCC provided for therein, but only upon the
condition, among others, that Grantor shall have executed and delivered to
Lender this Security Agreement.

AGREEMENT

Accounts, provided that such collection is performed in a prudent and
businesslike manner, and Lender may, upon the occurrence and during the
continuation of any Event of Default or potential Event of Default and without

Security Agreement; (b) discharge due to any disability of CHCC; (c) any
defenses of CHCC to obligations under the Post-Confirmation Agreements not

Agreement is sought to be enforced; (d) the benefit of any act or omission by
Lender which directly or indirectly results in or aids the discharge of CHCC
from any of the Secured Obligations by operation of law or otherwise; (e) all
notices whatsoever, including, without limitation, notice of acceptance of this

requirement that Lender exhaust any right, power or remedy or proceed against

assert or obtain a claim for personal judgment against CHCC, for all or any
part of the Secured Obligations; (ii) make any effort at collection or
enforcement of all or any part of the Secured Obligations from CHCC (iv) file

desirable to perfect and protect such security interest have been duly taken.

all such further instruments and documents and take such further action as
Lender may reasonably deem desirable to obtain the full benefits of this
Agreement.

6.2 MAINTENANCE OF RECORDS. Grantor shall keep and
maintain at its own cost and expense satisfactory and complete records of the

Collateral, and Grantor will at all times use its best efforts to defend Lender
and the Collateral against all inconsistent claims and demands of others.

an interest (whether as owner, mortgagee, beneficiary under a deed of trust,
lien or otherwise), Grantor shall, whenever requested by Lender, use its best
efforts to obtain from such third party, in a form acceptable to Lender,
whatever waivers and subordinations that Lender in its sole discretion
requires, so as to ensure that Lender's rights in and to the Collateral are,
and will continue to be, prior and superior to the rights of any such third
party.

authorized representatives are authorized to enter upon any of Grantor's
business premises at reasonable hours for purposes of inspecting Grantor's
properties and collateral.

unpaid Secured Obligations;

FINALLY, upon payment in full of the Secured
Obligations, to Grantor or its representatives or as a court

8. LIMITATION ON LENDER'S DUTY IN RESPECT OF COLLATERAL. Lender
shall be deemed to have acted reasonably in the custody, preservation and
disposition of any of the Collateral if it takes such action as Grantor
requests in writing, but failure of Lender to comply with any such request
shall not in itself be deemed a failure to act reasonably, and no failure of
Lender to do any act not so requested shall be deemed a failure to act
reasonably.

or otherwise reactivated or converted to a Chapter 7 case or should the Plan be
substantially modified. This Security Agreement shall continue to be effective
or be reinstated, as the case may be, if at any time payment and performance of
the Secured Obligations, or any part thereof, is, pursuant to applicable law,
rescinded or reduced in amount, or must otherwise be restored or returned by
any obligee of the Secured Obligations, whether as a "voidable preference,"
"fraudulent conveyance," or otherwise, all as though such payment or
performance had not been made. In the event that any payment, or any part
thereof, is rescinded, reduced, restored or returned, the Secured Obligations
shall be reinstated and deemed reduced only by such amount paid and not so
rescinded, reduced, restored or returned.

SECURITY AGREEMENT

THIS SECURITY AGREEMENT dated as of July 12, 1995, is made by COMMUNITY
HEALTH COMPUTING CORP., a Delaware corporation ("Grantor"), in favor of ADAC
LABORATORIES, a California corporation ("Lender").

RECITALS

A. On December 7, 1994, Grantor and COMMUNITY HEALTH COMPUTING,
INC., a Texas corporation ("CHCI"), commenced separate cases under Chapter 11
of Title 11 of the United States Code (the "Bankruptcy Code") by filing
voluntary petitions with the United States Bankruptcy Court for the Southern
District of Texas, Houston Division (the "Bankruptcy Court"), which Chapter 11
cases are now pending as Case Nos. 94-48483-H2-11 and 94-48484-H3-11 and are
collectively hereinafter referred to as the "Chapter 11 Case". No trustee was
appointed, and Grantor and CHCI operated their respective businesses and
remained in possession of their property as debtors-in-possession during the
term of the bankruptcy. At the time this Security Agreement becomes effective,
Grantor and CHCI will be operating their businesses as reorganized Debtors
pursuant to a confirmed Plan of Reorganization (the "Plan").

B. On December 7, 1994, Grantor, CHCI and Lender entered into a
Post-Petition Financing Agreement (the "Post-Petition Financing Agreement")
pursuant to which Lender has provided Grantor and CHCI with debt financing,
secured by a lien on substantially all of their assets.

C. Grantor and CHCI have prepared and reviewed with Lender, and
have filed with the Bankruptcy Court, their proposed Plan, together with a
Disclosure Statement with respect thereto. Capitalized terms used but not
defined in this Security Agreement shall have the meanings given to them in the
Plan.

D. The Plan contemplates, among other things, (i) that Grantor,
CHCI and Lender shall enter into a "Modification of Loan Agreements", pursuant
to which Grantor and CHCI will issue a secured promissory note (the
"Replacement Note") and enter into this Security Agreement and the CHCI
Security Agreement, as defined below, in relation thereto, (ii) that CHCI and
Lender shall enter into a "Post-Confirmation Loan Agreement", pursuant to
which CHCI will issue a secured promissory note (the "CHCI Note") and enter
into a security agreement (the "CHCI Security Agreement") in favor of Lender,
and (iii) that Grantor, CHCI and Lender shall enter into a Series A Preferred
Stock Purchase Agreement (the "Acquisition Agreement"), providing for (a) the
forgiveness by Lender of the obligations of Grantor and CHCI to pay an
aggregate of four million dollars ($4,000,000) of principal and interest owed
to Lender under the Post-Petition Financing Agreement and/or that certain Loan
Agreement dated as of November 30, 1994 among Grantor, CHCI and Lender and (b)
in consideration of such forgiveness of indebtedness, the issuance by Grantor
to Lender of an aggregate of four million (4,000,000) shares of a new series of
Grantor's preferred stock, designated Series A

1.
<PAGE> 20

Preferred Stock, which, together with any shares of common stock that may be
issued to Lender upon voluntary conversion thereof and certain options to
purchase shares of common stock to be issued pursuant to Lender's direction,
will constitute all of the outstanding equity securities of Grantor immediately
after the Closing. (The Modification to Loan Agreements, the Replacement Note,
the Post-Confirmation Loan Agreement, the CHCI Note, the CHCI Security
Agreement, this Security Agreement, the Acquisition Agreement and other related
agreements are referred to herein as the "Post-Confirmation Agreements".)

E. Grantor is the sole shareholder of CHCI and as such will
receive substantial direct and indirect benefit from the CHCI Note, the
Post-Confirmation Loan Agreement and other financial accommodations made by
Lender to CHCI pursuant to the Post-Confirmation Agreements.

F. Lender is willing to enter into the Replacement Note and the
other Post-Confirmation Agreements and to make the loans and other financial
accommodations to Grantor and CHCI provided for therein, but only upon the
condition, among others, that Grantor shall have executed and delivered to
Lender this Security Agreement.

5.4 COLLATERAL LOCATION. The Collateral is located at
Grantor's principal place of business, Houston, Texas and all of Grantor's
books and records, including, but not limited to, the books and records
relating to Grantor's Accounts are and will be kept and maintained at Debtor's

at all times use its best efforts to defend Lender and the Collateral against
all inconsistent claims and demands of others. Whenever any Collateral is
located upon premises in which any third party has an interest (whether as
owner, mortgagee, beneficiary under a deed of trust, lien or otherwise),
Grantor shall, whenever requested by Lender, use its best efforts to obtain
from such third party, in a form acceptable to Lender, whatever waivers and
subordinations that Lender in its sole discretion requires, so as to ensure
that Lender's rights in and to the Collateral are, and will continue to be,
prior and superior to the rights of any such third party.

7. RIGHTS AND REMEDIES ON DEFAULT.

7.3 APPLICATION OF PROCEEDS. The Proceeds of any sale,
disposition or other realization upon all or any part of the Collateral shall

the Secured Obligations, or any part thereof, is, pursuant to applicable law,
rescinded or reduced in amount, or must otherwise be restored or returned by
any obligee of the Secured Obligations, whether as a "voidable preference,"

shall be reinstated and deemed reduced only by such amount paid and not so
rescinded, reduced, restored or returned.

("CHCI"), and ADAC LABORATORIES, a California corporation ("LENDER").

RECITALS

A. On November 30, 1994, CHCC, CHCI and Lender entered into a
LOAN AGREEMENT (the "PRE-PETITION LOAN AGREEMENT"), pursuant to which Lender

all of their assets, in the aggregate amount of approximately $3,498,000, none
of which is presently outstanding.

under Chapter 11 of Title 11 of the United States Code (the "Bankruptcy Code")
by filing voluntary petitions with the United States Bankruptcy Court for the
Southern District of Texas, Houston Division (the "Bankruptcy Court"), which
Chapter 11 cases are now pending as Case Nos. 94-48483-H2-11 and 94-48484-H3-11
and are collectively hereinafter referred to as the "Chapter 11 Case". No
trustee has been appointed, and CHCC and CHCI continue to operate their
respective businesses and are in possession of their property as
debtors-in-possession.

C. On December 7, 1994, CHCC, CHCI and Lender entered into a
Post-Petition Financing Agreement (the "Post-Petition Financing Agreement")

amounts. All amounts owed under the Loan Agreements and not forgiven hereby
shall remain payable by CHCC and CHCI as provided below.

2. REPLACEMENT NOTE AND SECURITY AGREEMENTS FOR UNPAID BALANCE.
The unpaid principal balance outstanding under the Post-Petition Financing
Agreement after the above-described forgiveness shall be represented by and
governed by the terms of a new five-year, 12% Promissory Note in the form

Reorganization, or the assets thereof, for purposes of repayment of the Note.

3. TERMINATION OF LOAN AGREEMENTS. Immediately upon the
effectiveness of the above-described transactions, the parties, by mutual
consent, hereby terminate each of the Loan Agreements and any and all related
security agreements, financing statements and other documents or instruments

(BW) (ADAC LABORATORIES) (ADAC) ADAC Announces Completion of Acquisition of
Community Health Computing

MILPITAS, California -- July 13, 1995 -- ADAC Laboratories
(NASDAQ: ADAC) announced today the completion of its acquisition of Community
Health Computing (CHC) of Houston, Texas at a cost of approximately $16.5
million plus expenses of approximately $1.9 million.

Mr. David L. Lowe, Chief Executive Officer, stated, "ADAC has
acquired all rights to CHC's product portfolios for the laboratory information
systems and radiology information systems markets. Furthermore, the
acquisition includes all associated customer support contracts which represent
$12 million in recurring annual revenue. This acquisition marks ADAC's
entrance into the $400 million laboratory information systems market,
increasing our addressable market by 75 percent. ADAC's immediate focus in
laboratory information systems will be the completion of LabStat(TM), new
client-server, open architecture product. CHC has invested 180 staff years in
developing LabStat which is expected to be available for customer delivery in
the first half of 1996."

Mr. Lowe continued, "ADAC's existing radiology information
systems product line, which includes QuadRIS(TM), is significantly strengthened
with the addition of CHC's RadStat(TM) product, creating the most dominant
product line in the radiology information systems industry."

Mr. Lowe concluded, "The acquisition of CHC brings ADAC over
160 installed customer sites in the laboratory information systems market and
300 installed customer sites in the radiology information systems market. The
combination of this installed base and a broad product offering of technically
advanced clinical healthcare systems represents a significant milestone in our
strategic plan to aggressively grow our healthcare information systems
business."

As previously announced, Mr. Mark Lamp has been appointed
President, ADAC HealthCare Information Systems, the new division combining ADAC
SD&G Healthcare Systems and CHC. The headquarters for ADAC HealthCare
Information Systems will be in Houston, Texas.

ADAC Laboratories is recognized as the world market share
leader in nuclear medicine and the leading supplier of radiology information
systems in North America. ADAC was one of only six manufacturing companies
nationwide to receive a site visit for the Malcolm Baldrige National Quality
Award in 1994. The company headquarters are in Milpitas, California.
